It's not as simple as that. America had an extremely isolationist strategy at the turn of last century, and we still ended up involved in the two largest conflicts in history.

While I would say we are a bit too involved in the world military scene, there is a certain preventative logic to it.

Preventative? Oh, you mean like creating severe blowback, funding dictators, aiding financially in a modern religious holocaust, monopolizing other countries' resources by force, crippling trade with an ally of the world's other largest superpowers, all while going far beyond broke?

I bet that'll prevent all kinds of threats to the US in the future.

What do you think is gonna happen when our economy inevitably crashes and Russia and China finally get fed up with our government's bullying?
